Condense_k

Purpose

condense matrix K to a reduced set idr of dofs by condensing out dofs idc

Synopsis

krr = Condense_k (k,idr,idc)

Description

CONDENSE_K condense matrix K to a reduced set idr of dofs by condensing out dofs idc
  KRR = CONDENSE_K (K,IDR,IDC)
  the function condenses the stiffness matrix K to a reduced set of dofs as specified
  in list or row vector IDR by condensing out the dofs in list or row vector IDC;
  the condensed stiffness matrix is KRR
